Thanks. Yes, I did use the search in edit mode, but, as I said, every one of the FamilySearch.org links contained the text string "ark" which was the only clue I got in the info column, so I had to check all fourteen of those FamilySearch.org links. Naturally, it was the last one which was no longer a valid link. But, next time, I will check to see if the "ark" immediately follows the http:// or https://. I didn't know that before, but I know it now. I see it says that on the DBE 961 info page. Should have looked there. Next time, I will also look there first to see if there are any helpful hints.
